Owners of the CMMG Dissent BR47 in 7.62x39mm generally speak well of the fit and finish relative to competing AR-pattern 7.62x39 builds. The BR47 platform is noted for reliable feeding from AK-pattern magazines, which is a common sticking point on other AR-style 7.62x39 rifles, and most owners report the Dissent handles this without chronic issues.

The ambidextrous controls draw consistent praise from left-handed shooters and those who prefer a fully ambi setup. The pinned and welded 14.3-inch barrel configuration gets a practical nod from buyers in states with restrictions, though some owners wish for a standard 16-inch barrel option without the muzzle device permanently attached.

The CMMG price point positions the Dissent above budget AR builds, and opinions split on whether the platform justifies that premium. Fans of the brand point to the machining quality and the ambi layout as worth the cost; skeptics feel comparable reliability is available for less.
